Sergio Busquets praised Arsenal and warned that Barca will have to be on their mettle in the Nou Camp.

He said: “Physically they were very good, as they were tactically in the first half, but in the second we were much better. If they wanted to take risks, well so did we. That’s what happened in the second half and we took good advantage of it.

“We have a lot of respect for them for the return game. We know that this result is a really good one, but they can score against us at any given moment.”
